investment significantly accelerated deployment timelines and introduced cutting-edge fiber optic technology, setting new benchmarks in transatlantic data speeds. This case demonstrates that even privately led initiatives often rely on public-sector collaboration to navigate regulatory and geopolitical challenges.
3.5 CASE STUDY: ELLALINK SUBMARINE CABLE
The EllaLink Submarine Cable provides a direct connection between Europe and Latin America, linking Portugal, Brazil, Cape Verde, Mauritania, and French Guiana. Unlike traditional transatlantic systems that route through the United States, this 6,000-kilometer cable was strategically developed to enhance data sovereignty and improve direct connectivity between the two continents. The European Union and the Brazilian government played a role in supporting the project, ensuring its strategic importance. Private sector investment made it possible to integrate advanced data transfer technologies, benefiting cloud service providers, businesses, and research institutions. The EllaLink system showcases how PPPs can be leveraged to strengthen regional connectivity while aligning with national security objectives.
3.6 CASE STUDY: SEA-ME-WE 6 SUBMARINE CABLE SYSTEM
The SEA-ME-WE 6 submarine cable spans 19,200 kilometers and connects Southeast Asia, the Middle East, and Western Europe. This multinational project required cooperation between 14 major telecom providers and multiple national governments, ensuring cost-effective construction while addressing regulatory concerns. The cable is crucial for reducing congestion on existing routes, improving connectivity for digital economies, and strengthening network resilience. Governments in participating nations, including India, Egypt, and France, facilitated approvals and security measures to protect the infrastructure.
3.7 CASE STUDY: ASIA-AMERICA GATEWAY (AAG) SUBMARINE CABLE SYSTEM
The Asia-America Gateway (AAG) Submarine Cable System, a 20,000-kilometer network connecting Southeast Asia with the United States, is another example of a successful PPP. Unlike single-nation projects, the AAG cable involves a consortium of both state-owned and private telecom companies, such as Telekom Malaysia and PLDT in the Philippines. Governments played an essential role in facilitating regulatory approvals and, in some cases, provided direct
investment to ensure the project’s feasibility. The AAG system is strategically vital, as it reduces reliance on other trans-Pacific cables, enhances regional connectivity, and fosters economic development in participating nations. Beyond individual case studies, PPPs play a crucial role in ensuring the security and resilience of subsea cables. Governments are increasingly involved in cable projects to protect national security interests and mitigate cyber threats. The United States, for example, has intervened in projects like the Southeast Asia-Japan Cable to prevent foreign state influence over critical communication infrastructure. This growing awareness underscores the fact that subsea cables are not merely commercial assets but strategic components of global connectivity. Looking ahead, PPPs are expected to play a vital role in shaping the next generation of subsea networks. Emerging technologies such as AI-driven cable management systems and quantum-secure communication networks will require substantial investment, research, and regulatory oversight. Public-private collaboration will be key to ensuring that these innovations are deployed securely and efficiently.
4. THE BENEFITS OF PUBLIC-PRIVATE PARTNERSHIPS IN SUBMARINE CABLES
Public-Private Partnerships offer several key benefits in the submarine cable industry: 1. Risk Sharing: One of the primary advantages of PPPs is the distribution of financial and operational risks between the public and private sectors. This approach enables large-scale projects, such as the Coral Sea Cable System, which would be too risky for a single entity to undertake alone. 2. Access to Capital and Expertise: PPPs allow governments to leverage private investment and technical expertise. In the case of the Hawaiki cable, private sector efficiency in design, deployment, and maintenance was complemented by public support to ensure the project met national infrastructure goals. 3. Alignment with National Interests: Governments can ensure that submarine cable projects align with national security and economic development goals. The New Zealand government’s investment in the Hawaiki cable ensured that the project supported the country’s broadband objectives. 4. Enhanced Infrastructure Development: PPPs can accelerate the deployment of critical infrastructure, especially in underserved regions. The Asia-America Gateway improved connectivity for multiple Southeast Asian countries, fostering regional economic growth. JULY 2025 | ISSUE 143
